In the sales data processing device for accumulating the number of sales of corresponding products, the instruction means instructs free registration.

The registration processing control means, when the product identification data is input in a state where free registration is instructed by the instruction means,
The predetermined registration process is performed assuming that the unit price of the product corresponding to the product identification data is 0, and the number of sales as free registered products corresponding to the product identification data is accumulated.

[Operation] The operation of the means of the present invention is as follows.

It has storage means for storing unit prices and sales quantities for each product, and when product identification data is input, reads out the unit price of the corresponding product in the storage means and performs a predetermined registration process. In a sales data processing apparatus for accumulating the number of sales of corresponding products, free registration is instructed by the instruction means, and when the product identification data is input in a state where the free registration is instructed, the sales data processing device corresponds to the product identification data. The predetermined registration process is performed assuming that the unit price of the product is 0, and the total number of sales as a free registered product corresponding to the product identification data is performed by the registration process control means.

Therefore, the free registration process can be accurately performed with a simple operation, and the number of sales of the products registered for free can be accumulated.

Embodiment An embodiment will be described below with reference to FIGS. 1 to 5.

FIG. 1 is a block diagram of a sales data processing device. A CPU 1 processes various types of sales data input from a key input unit 2 according to a program stored in a ROM 3 in advance, and stores the processing results in a RAM 4. , Display on the display unit 5 and printing by the printing unit 6 are controlled.

The input control unit 7 scans the key operation status of the key input unit 2, generates a code corresponding to the operation key, and
Output to The display control unit 8 and the print control unit 9 respectively generate a display signal and a print signal in accordance with the data (code) to be displayed and printed, display the display signal on the display unit 5, and make the print unit 6 print.

The key input unit 2 is used for setting (P), registration (R), power supply OF
F, mode switch SW for switching and setting each mode of inspection (X) and settlement (Z), numeric keys for inputting numerical data
2a, a PLU key 2b indicating that the numerical value input by the numeric key 2a is a PLU No., a cash / deposit key 2c for instructing opening of a cash drawer 10 and closing of one registration, etc. And various keys such as a free registration key 2d for instructing free registration processing.

When the free registration key 2d is operated, the entered PL
A free registration flag F in the CPU 1 is set to indicate that the U No. is a PLU No. corresponding to a product requiring free registration processing.

In the RAM 4, various memories such as a product-specific memory M1 for registering sales data for each product, a free registration memory M2 for storing predetermined data for free registration, and a work memory M3 are formed.

As shown in FIG. 2, the product-specific memory M1 has areas for storing the unit price, the total number of sales, the total number of free services, the total amount of sales, and the number of stocks for each PLU No. of each PLU product. I have.

During the normal registration process, when the PLU No. is input, the total sales quantity of the corresponding product is increased by 1, the inventory quantity is decreased by 1, and the total sales amount is updated by the unit price. Further, when a free registration process is instructed by the free registration key 2d, if a PLU No. is input, the total number of free services of the corresponding product is increased by one and the number of stocks is decreased by one. That is, by not updating the total sales amount, the product is registered in a form provided free of charge.

As shown in FIG. 2, the free registration memory M2 stores, as predetermined data for free registration, the total sales amount of one transaction,
Each area has a service rate and a service limit amount.

The total sales amount for one transaction is data in which the unit price corresponding to the PLU No. input during the normal registration process is read from the product memory M1 and accumulated, and the closing operation for one transaction was performed. Cleared when. The service rate is, for example,
This is a value such as 10%, which is preset data.

As the service limit amount, when the free registration key 2c is operated, the total sales amount of one transaction is multiplied by the service rate, the result of the multiplication is initially set as the service limit amount, and the range of this service limit amount is set. Free registration is done within. That is, each time the PLU No. is entered after the free registration key 2d is operated and the free registration process is performed, the initially set service limit amount is reduced by the unit price of the product related to the free registration process. Based on the result of the subtraction, it is determined whether the free registration process requested next is possible or not.

Next, the operation of the embodiment will be described with reference to FIGS.

First, a process when the free registration key 2d is operated will be described with reference to FIG.

When the free registration key 2d is operated under the registration mode, the CP
U1 sets a free registration flag F based on the program in ROM2 (step S41). Then, the total sales amount of one transaction and the service rate in the free registration memory M2 are read and multiplied, and the result of the multiplication is initially set in the service limit amount area (step S42). Next, the result of the multiplication is displayed on the display unit 5 as the service limit amount (step S43), and the process ends.

Next, the PLU key 2b is operated together with the numeric key 2a to set the PLU No.
The process performed when "" is input will be described with reference to FIG.

When the PLU No. is operated under the registration mode, CPU 1
First, it is determined whether or not the free registration flag F is set (step S51). As a result, the free registration flag F
If is not set, the
Performs a normal series of registration processing, such as adding 1 to the total sales quantity of the product corresponding to the PLU No., subtracting 1 from the stock quantity, updating the total sales amount by the unit price, and printing the receipt of characters and unit prices. (Step S52). Then, the total sales amount of one transaction in the free registration memory M2 is
The product is updated by the unit price of the product corresponding to the input PLU No. (step S53), and the process ends.

In step S51, when it is determined that the free registration flag F is set, whether the value obtained by subtracting the unit price of the product corresponding to the input PLU No. from the current service limit is 0 or more. Is determined (step S54). If the result is 0 or more, the value is stored as the next service limit in the service limit area (step S55). Then, the total number of free services of the product corresponding to the input PLU No. is incremented by 1 (step S56),
The number of stocks is decremented by one, and a receipt indicating that the free service is provided is printed (step S57), and the processing is terminated.

If it is determined in step S54 that the value is not 0 or more, it means that a free registration larger than the service limit has been requested, so that it is displayed that free registration cannot be performed (step S58), and the processing ends. I do.

As described above, by operating the free registration key 2d, a series of free registration processes are automatically executed, so that it is not necessary to perform a correction operation associated with the conventional free registration, and the burden on the operator is reduced. And you can register accurately for free.

Next, the processing of FIGS. 3 and 4 will be specifically described with reference to FIG.

When "1" is input using the numeric key 2a and the PLU key 2b is operated, the character "tape recorder" of the product corresponding to PLU No. 1 and its unit price "23000" are displayed and receipt printed.

Next, when the free registration key is operated, the multiplication value “2300” of the unit price “23000” of the tape recorder and the service rate of 10% is obtained.
Appears with the message "Service limit".

Next, input “10” using the numeric key and operate the PLU key. The unit price of the product corresponding to PLU No. 10 is “5000”.
Since the service limit is larger than "2300", a message "Torokufuka" is displayed.

Therefore, when "100" is input using the numeric key and the PLU key is operated, the character "cassette tape" of the product corresponding to PLU No. 100 and the unit price "230" are displayed, and the receipt is printed. At this time, a message "free service" is also printed on the receipt.

When the cash / deposit key is operated, the contents shown in the figure are displayed and the receipt is printed.

As described above, since it is automatically determined whether or not the free service is available, the burden on the operator is reduced.

The present invention is not limited to the above-described embodiment, but can be applied to, for example, a model in which PLU registration is performed by a barcode reader or the like. In addition, it can be applied not only to a stand-alone electronic register but also to a POS terminal.

[Effects of the Invention] According to the present invention, free registration processing can be accurately performed with a simple operation, and it is not necessary to perform a correction operation for performing free registration as in the related art, and the burden on the operator is reduced. . In addition, since the number of sales of commodities registered for free can be accumulated, the sales number of commodities registered for free can be known.
